We have a 5 year old spayed female cat who refuses the litter box. Weve tried multiple litter, new boxes, moving boxes, locking her up all day - nothing works. We have taken her to get checked and they found nothing. She uses a pee pad but now my.other cats have started attempting to use it. If I do not catch it in time, she finds some carpet space. Its ruining our floors and I cant so it anymore, unfortunately. Another rescue mentioned euthanasia but its so hard bc shes beautiful and the sweetest. Would you have space for her?
